Earthsmith

The creature swayed back and forth foolishly, supporting the bulk of his weight first on one extremity and then on the other. His face which had a slight rosy tint anyway got redder.

"Come, come. Planet? Name?" The registrar was only a machine, but the registrar could assume an air of feminine petulance. "We want to keep the line moving, so if you will please --"

The creature drew a deep breath and let the two words come out in a rush. "Earth, Smith," he said. Being nervous, he could not modulate his voice. Unable to modulate his voice, he heard the words come out too deep, too loud.

Nobody at the Interstellar Space School had ever heard of Earth so naturally they treated Smith with contempt -- or was it an innate fear. . . ?
